2.0 Applicable standards and reference documentation

The drive has been developed as a system peripheral to the highest standards of design and construction. The

drive depends upon its host equipment to provide adequate power and environment in order to achieve opti-

mum performance and compliance with applicable industry and governmental regulations. Special attention

must be given in the areas of safety, power distribution, shielding, audible noise control, and temperature regu-

lation. In particular, the drive must be securely mounted in order to guarantee the specified performance char-

acteristics. Mounting by bottom holes must meet the requirements of Section 8.5.

2.1 Standards

The Cheetah 10K.7 FC family complies with Seagate standards as noted in the appropriate sections of this

manual and the Seagate Fibre Channel Interface Manual, part number 77767496.

The Cheetah 10K.7 FC disc drive is a UL recognized component per UL1950, CSA certified to CAN/CSA

C22.2 No. 950-95, and VDE certified to VDE 0805 and EN60950.

2.1.1 Electromagnetic compatibility

The drive, as delivered, is designed for system integration and installation into a suitable enclosure prior to

use. As such the drive is supplied as a subassembly and is not subject to Subpart B of Part 15 of the FCC

Rules and Regulations nor the Radio Interference Regulations of the Canadian Department of Communica-

tions.

The design characteristics of the drive serve to minimize radiation when installed in an enclosure that provides

reasonable shielding. As such, the drive is capable of meeting the Class B limits of the FCC Rules and Regula-

tions of the Canadian Department of Communications when properly packaged. However, it is the user’s

responsibility to assure that the drive meets the appropriate EMI requirements in their system. Shielded I/O

cables may be required if the enclosure does not provide adequate shielding. If the I/O cables are external to

the enclosure, shielded cables should be used, with the shields grounded to the enclosure and to the host con-

troller.

2.1.2 Electromagnetic susceptibility

As a component assembly, the drive is not required to meet any susceptibility performance requirements. It is

the responsibility of those integrating the drive within their systems to perform those tests required and design

their system to ensure that equipment operating in the same system as the drive or external to the system

does not adversely affect the performance of the drive. See Section Table 11, DC power requirements.

2.2 Electromagnetic compliance

Seagate uses an independent laboratory to confirm compliance with the directives/standards for CE Marking

and C-Tick Marking. The drive was tested in a representative system for typical applications. The selected sys-

tem represents the most popular characteristics for test platforms. The system configurations include:

• Typical current use microprocessor

• 3.5-inch floppy disc drive

• Keyboard

• Monitor/display

• Printer

• External modem

•Mouse

Although the test system with this Seagate model complies with the directives/standards, we cannot guarantee

that all systems will comply. The computer manufacturer or system integrator shall confirm EMC compliance

and provide the appropriate marking for their product.

Electromagnetic compliance for the European Union

If this model has the CE Marking it complies with the European Union requirements of the Electromagnetic

Compatibility Directive 89/336/EEC of 03 May 1989 as amended by Directive 92/31/EEC of 28 April 1992 and

Directive 93/68/EEC of 22 July 1993.

Australian C-Tick

If this model has the C-Tick Marking it complies with the Australia/New Zealand Standard AS/NZS3548 1995

and meets the Electromagnetic Compatibility (EMC) Framework requirements of Australia’s Spectrum Man-

agement Agency (SMA).

Korean MIC

If this model has the Korean Ministry of Information and Communication (MIC) logo, it complies with paragraph

1 of Article 11 of the Electromagnetic Compatibility (EMC) Control Regulation and meets the Electromagnetic

Compatibility Framework requirements of the Radio Research Laboratory (RRL) Ministry of Information and

Communication Republic of Korea.

Taiwanese BSMI

If this model has the Chinese National Standard (CNS) 13438 marking, it complies with Chinese National Stan-

dard (CNS) 13438 and meets the Electromagnetic Compatibility (EMC) Framework requirements of the Tai-

wanese Bureau of Standards, Metrology, and Inspection (BSMI).

2.3 European Union Restriction of Hazardous Substances (RoHS)

A new law, the European Union Restriction of Hazardous Substances (RoHS) directive, will restrict the pres-

sence of chemical substances, including Lead (Pb), in electronic products effective July 2006. The directive’s

requirements have not been finalized. This drive is manufactured with components and materials that are

expected to comply with the RoHS directive when the directive takes effect.

3.0 General description

Cheetah 10K.7 FC drives combine giant magnetoresistive (GMR) heads, partial response/maximum likelihood

(PRML) read channel electronics, embedded servo technology, and a Fibre Channel interface to provide high

performance, high capacity data storage for a variety of systems including engineering workstations, network

servers, mainframes, and supercomputers.

Cheetah 10K.7 FC drives support the Fibre Channel Arbitrated Loop (FC-AL) and SCSI Fibre Channel Proto-

col as described in the ANSI specifications, this document, and the Fibre Channel Interface Manual (part num-

ber 77767496) which describes the general interface characteristics of this drive. Cheetah 10K.7 FC drives are

classified as intelligent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI stan-

dard.

Never disassemble the HDA and do not attempt to service items in the sealed enclosure (heads, media, actu-

ator, etc.) as this requires special facilities. The drive contains no parts replaceable by the user and opening

the HDA for any reason voids your warranty.

Cheetah 10K.7 FC drives use a dedicated landing zone at the innermost radius of the media to eliminate the

possibility of destroying or degrading data by landing in the data zone. The drive automatically goes to the

landing zone when power is removed.

An automatic shipping lock prevents potential damage to the heads and discs that results from movement dur-

ing shipping and handling. The shipping lock automatically disengages when power is applied to the drive and

the head load process begins.

A high-performance actuator assembly with a low-inertia, balanced, patented, straight arm design provides

excellent performance with minimal power dissipation.
